SPECIFICATION forming part of Letters Patent No. 296,848, dated April15, 1884.

Application led November 2l, 1883. (No model.)

To @ZZ whom t may concern,.-

Be it known that I, JOHN Knnnnrnr., of Detroit, in the county of Wayneand State of Michigan, have invented new and useful Improvements inCapsnle-Immersing Machines; and I do hereby declare that the followingis a full, clear, and enact description thereof, reference being had tothe accompanying draw-` ings,which forni a part of this specification.

This invention relates to certain new` and useful improvements in theconstruction of devices especially designed for immersing capsule-moldsin a gelatine solution; and the invention consists, first, in thepeculiar constructionand arrangement of parts forming the heatingjacketwhich receives the pan containing the gelatine which is to be kept insolution; second, in the peculiar construction and arrangement ofdevices for agitating or stirring such solution, or the solutioncontained in the pan, to prevent the forming of a crust upon itssurface; third, in the devices employed for stirring the capsule-moldsand immersing such molds in the solution, and, fourth, in the peculiarconstruction, arrangement, and combinations ot' thev various parts, allas more fully hereinafter set forth.

Figure 1 is a perspective view of my improved device. Fig. 2is averticalsection thereof. t

In the accompanying drawings, which form a part of this specification, Arepresents a suitable stand-pipe,which supports the steamjacket B, andinto which steam has access through the pipe A from any convenientsource of supply. Around this stand-pipe A, I place a coil-spring, C,which supports a sleeve, D, from which latter rises a series ofbrackets, E, upon the upper ends of which is detachably secured thering-plate F. In this ring I secure the downwardly-projectingstirring-coil G, which carries avertically-stirring bar, H. One ormoreof these stirring appliances maybe used, as the size of the dippingpan Imay require, in order thatin operation the solution contained thereinshall `be sufficient-ly agitated to prevent the formation of a crustupon the surface of the solution.

If desired, the sleeve D may be connected to a treadle or foot-lever, sothat the operator may, by pressing upon the leve1,cause a partialrotation of such sleeve upon the pipe A, and necessarily impart a likemotion to the stirrers Within the dipping-pan, as shown in the drawings.There power is convenient, a loose belt may be arranged in connectionwith this sleeve, so that such sleeve, together with the stirrers whichare indirectly connected thereto, as hereinbefore described, will have acontinuous movement, except at such times as When the capsule-mold plateis imposed upon the ring F, at -which time the belt will slip upon thesleeve.

In practice, the parts being constructed substantially as described, andstanding in the position shown in Fig.. l, the capsule-plate with itsmolds is placed upon the ring F, with the mold-pins projecting downward.By then pressing down upon this plate the mold-pins are immersed in thesolution, the stirrer H sliding vertically in the coil-stirrer. Theoperator then allows the spring C to exert its force so as to graduallyraise the parts which have been depressed, and thereby remove thecapsule-molds from the solution. It it is desired to regulate the depththat such moldpins shall be inserted in the solution, such can readilybe done by having adjusting-stops between the ring and top of theheating-jacket, or by having a regulating-stop so arranged thatthesleeve can be depressed to a greater or less degree, as desired. Tokeep` the solution within the pan in its soluble state, steam isadmitted into the jacket through the pipe A, the radiation from whichwill generally keep the gelatine at the desired consistency; but shouldit prove too hot, water may be placed in the jacket between it and thepan holding the solution. A

What I claim as my invention is# l. A device for dipping capsule-molds,con sisting of a vertically moving supportingi'rame carrying stirrersadapted to recede and advance as the molds are immersed and Withdrawn,substantially as set forth.

2. In a device for dipping capsule-molds, the combination, with asuitable vessel for containing the solution from which the capsules areto be formed, of a vertically-moving supporting-frame carrying.;`stilrers, and mechanism by means of which such stirrers are rotated orpartially rotated Within the dipping vessel, substantially as described.

3. In a device for dipping capsule-molds, the combination of thesteam-jacket B, supporting frame or ring E, with the pan I and stirrersII G, substantially as set forth.

4. In a capsule-dipping` device, the combination of the pan I with twostirrers, one of which moves vertically independent of the other, andmeans for rotating the same, substantially as described.

5. In a device for dipping capsule-molds, a
